Wheel Change Switch; Warning - Mercedes-Benz 500 SL Owner's Manual

Warning!

The jack is designed exclusively for
jacking up the vehicle at the jack
tubes built into either side of the
vehicle. To help avoid persona!
injury, use the jack only to lift the
vehicle during a wheel change. Never
get beneath the vehicle while it is
supported by the jack. Keep hands
and feet away from the area under
the lifted vehicle. Always firmly set
parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake
while the vehicle is raised. Be certain
that the jack is always vertical when
in use, especially on hills. Always try
to use the jack on level surface. Be
sure that the jack arm is fully
inserted in the jack tube. Always
lower the vehicle onto sufficient
capacity jackstands before working
under the vehicle.

when changing wheels, the roll bar
